How hard was it to pull the pistons, etc. out of the calipers and then put everything back together? Did you use some type of heat resistant tape to cover those holes while they were in the oven?

Breaking down the calipers is actually very easy. By the time I got to the third wheel, I could have the entire assembly removed from the car and completely broken down in 10-15 minutes. Rebuilding was as simple as doing everything in reverse. Just be prepared to get dirty.

As for the tape I used, home depot/lowes sells metal based tape for HVAC ducts. It's basically aluminum foil with adhesive on one side. It's pretty cheap and worked great.
